Just so you know even with a fanless cooler you would still need good case ventilation or its just not gonna cool. Your best bet is to get a big cooler with 120mm fan which are fairly quiet and just keep it at low RPMs.
Thanks. I'll look at those. I think I might like to go with one that has a fan, so does anyone know of a good heatsink with a fan that cools well and automatically adjusts its RPM by the CPU temperature? Edit: Sorry, I didn't notice the one you suggested had a fan included. I also noticed that it had a fan controller. I have a heatsink now with a fan and fan controller, but it is still pretty noisy and I would like one that adjusts manually based on CPU temps. Thanks.

My favorite for quiet heatsink are the two models from arctic cooling.
The Alpine 64 (AMD) or the Alpine 11 (intel) are the same heatsink, but each is equipped with stock mounts so you don't have to change the back plate like you do on most aftermarket units. This is especially useful if your replacing a heatsink on an already installed board. They cool a little better than stock and are a lot quieter. And they are cheap. They can be had for under $20 out the door. They also come with a 6 year warranty.
If you want something a thats cooler, but still quiet they have the Freezer 64/7. These guys are come in under $40 out the door. Again stock bracket, they are cool and very quiet. And a 6 year warranty.
